i heard it was over 400 but i saw a engine today with a consistant 350 on all 8 cylinders and it was a new(rebuilt) moter,whats the consensus? i do say ol'chap will you be haveing a totty with me tonight??? i guess ill go back to my roots and post like a freakin scholar since people cant read anything without correct punctuation and grammer...freaks

IIRC 400-425 is Ford's spec. 350 is a bit low but if the rings haven't yet seated (you said it was recently rebuilt) that would be expected. It takes a little while too. That being the case the uniformity is the big thing and the pressure will come up when the rings get seated. The compression ratio is 17.5:1.
